ABSTRACT
Since 1937 it was reported that changes in the state of consciousness caused by anesthetic can be monitored by electroencephalography (EEG). Later the bispectral index (BIS) and Entropy retook the concept, making it easier to interpretation through graphs and numerical rating. However, its use is only validated for some drugs. The following EEG records were taken from actual patients under general anesthesia in neurological surgery by two bipolar channels positioned according to the 10/20 system, A1-Fp1 and A2-Fp2. Records an awake and under the effect of drugs commonly used in anesthesia as propofol, sevoflurane and dexmedetomidine patient is included. The study of these images, in contrast to the entropy and bispectral index, to interpret the different waves and monitor the specific effects of each drug in real time, on brain states and neural mechanisms.REFERENCES
